Abstract

La présente invention concerne la navigation sur un tracé effectuée par un objet mobile et des systèmes de commande du mouvement prévus pour des machines-outils gérables par ordinateur. Linvention concerne une méthode de calcul des limites de vitesse, pour plusieurs commandes de mouvement, associées à une commande de mouvement afin de faire en sorte quun objet se déplace le long dune trajectoire. Une file dattente danticipation comprend plusieurs commandes de mouvement. Une première distance darrêt pour la première commande de mouvement est calculée en se fondant sur la distance entre un premier point cible et un premier point virtuel au-delà du premier point cible. Une deuxième distance darrêt pour la deuxième commande de mouvement est calculée en se fondant sur la distance entre un deuxième point cible et un deuxième point virtuel au-delà du deuxième point cible. Un dispositif de calcul modifie la limite de vitesse de la première commande de mouvement en réduisant la première distance darrêt selon la deuxième distance darrêt. La première commande de mouvement est ensuite transmise au dispositif de commande du mouvement.
